A nurse of spirit? (5)
I believe the answer is:
angel
I believe this is a double definition.
'a nurse' is the first definition.
(angel can informally mean a nurse)
'spirit?' is the second definition.
(I know that angel is a type of spirit)
'of' is the link.
(Other definitions for angel that I've seen before include "one might be recording" , "One backing theatre production" , "Glean (anag.)" , "Heavenly messenger" , "Seraph or cherub?" .)
